摘要
对管井降水从方案设计、成井工艺、影响因素及环境保护进行了分析,总结出一些管井降水在孔隙潜水中降水的技术经验,提出了对垂直渗透系数较小,但水平渗透系数较大的湿陷性黄土管井降水方法,对今后在类似地质条件施工降水具有一定的参考价值。
The paper analyzes the tube well dewatering from aspects of scheme design,well-completion technology,influential factors and environmental protection,summarizes tube well dewatering technology in phreatic hole water,and puts forward tube well dewatering methods of collapsible loose with smaller vertical permeable coefficient and bigger horizontal permeable coefficient,which has certain guidance for construction dewatering with similar geological conditions in future.
